Description
One, technical field
The present invention relates to a kind of filter, specifically a kind of film filter.
Two, background technology
The research of membrane filtration and use are existing for many years, are engaged in film filtering element research, the mechanism or the enterprise that produce and use the manufacturing enterprise of these element combinations produce Membrane filtering machines also a lot.The technical development of film filtering element is very fast, the price of film filtering element also reduces greatly, but the Membrane filtering machine technology does not have too big progress, the equipment of producing mainly due to prior art, can not give full play to the performance of film filtering element, can't improve filter capacity to greatest extent, prolong film filtering element stream time and service life, thereby can't reduce user's use cost, make the scope of application of membrane filtration further not enlarge.The reason that produces the problems referred to above mainly is a prior art does not have breakthrough on the acquisition of technology to the regeneration of membrane component.
What present most of film filter adopted is the backwash renovation process, and its workflow is as follows, sees Fig. 2:
Stoste is filtered by raw liquor pump 4 input membrane modules 2 from original fluid container 1, and the clean liquid after the filtration enters filtering tank 3, returns original fluid container 1 after the stoste of process membrane module 2 is concentrated; After membrane module work a period of time, owing to increase gradually attached to solid phase impurity on the filtering surface, the rate of filtration is more and more slower, must stop to filter, and the regeneration that recoils is handled; Backwashing pump 9 extracts the clean sap cavity that the clean liquid of fraction is squeezed into membrane module from filtering tank, oppositely, will dash from filtering surface, enter original fluid container through the concentrate pipe attached to solid phase impurity on the membrane filtration face by the membrane filtration face, the membrane filtration face obtains regeneration, can carry out the filter operation of following one-period.
There is following shortcoming in this periodicity backwash renovation process:
1, used the clean liquid of part as counter-flushing liquid, this part liquid also will carry out filtration treatment once more, thereby has reduced the complete machine disposal ability, has increased energy consumption; As use other liquid as counter-flushing liquid, before recoil or with the liquid emptying in the membrane module, or, cause the material waste with the mixing of the liquid backwash liquid in the membrane module; After the counter-flushing liquid operation is finished, also must the fluid discharge in the membrane module is clean, just can carry out the filter operation of following one-period, reduced the effective time, overall efficiency is descended;
2, in a filter cycle, some is squeezed in the filtering micropore by compacting gradually attached to the solid phase impurity on the filtering surface, this can not be come out by super backflush, the filter capacity of membrane module decreases, along with increasing of the micropore that loses filtration, these filtering micropores will be stopped up fully, have lost filtration, and whole membrane component finally will be scrapped;
3, the life-span of membrane module is depended on technical parameter, global design level of former liquid-solid phase impurity content, backwash process or the like.For the more stoste of solid phase impurity content, must shorten filter cycle, increase the backwash number of times and just can keep filter operation, at this moment the life-span of membrane component will shorten greatly.
In a word, the backwash renovation process of membrane filtration has reduced the operating efficiency of membrane module, has increased energy consumption, reduces the life-span of membrane module, has limited the scope of application of membrane filtration.Many materials that must improve filtering accuracy with membrane filtration are arranged, because impurity is more, the membrane component life-span is too short, can not directly use membrane filtration, makes the application of membrane filtration be very restricted.

Among the present invention, membrane module can be made up of a membrane module or a plurality of membrane module, and ball liquid separator, lose pump and ball-charging groove also can adopt one or more groups as required.When adopting two membrane modules, the outlet of first membrane module and second membrane module all is connected with filtering tank, and another outlet of first membrane module is connected with the inlet of second membrane module, is connected with ball-charging groove in the porch of first membrane module; Exit at second membrane module is connected with ball liquid separator, and the outlet of second membrane module is connected with the inlet of ball-charging groove with first membrane module by ball liquid separator, the pump of losing.
Adopt new inorganic membrane filtration renovation process among the present invention, at the membrane module filter process simultaneously, squeeze into the green-ball again of some with stoste, with green-ball again filtering surface is cleaned, film filter just can be regenerated while filtering like this, also can carry out batch (-type) regeneration, thereby can increase substantially the stream time of film filter and the filter capacity of unit interval; Prolong the life-span of film filtering element; Enlarged the scope of application of film filter simultaneously, can be used for some and want to use film filter to improve filter effect, reduce and filter cost in the past, and the existing occasion that membrane filtration technique can not achieve the goal or result of use is bad.
Use the workflow of film filter of the present invention as follows, see Fig. 1:
At the ball-charging groove an amount of green-ball again of packing into, stoste is filtered by raw liquor pump input membrane module from original fluid container before filtering, and the green-ball again in the ball-charging groove is squeezed into the stoste pipeline with the pump of losing simultaneously and stoste enters membrane component together; To be extruded distortion in the stoste passage be that filtering surface produces certain extruding force to conduit wall to green-ball again, when the regeneration ball is promoted forward by stoste, just filtering surface had cleaning action; The stoste of regeneration ball front by filtering surface produce a spot of, also not have complete attached to the solid phase impurity on the filtering surface be attracted to again on the green-ball or be reproduced ball push away forward catch up with and again green-ball leave membrane module by the stoste passage together; At the concentrated solution outlet place of membrane module, ball liquid separator is housed, allow concentrated stoste return original fluid container, green-ball enters the pump of losing after then cleaning in ball liquid separator again, is driven into membrane module again; Clean liquid after the filtration enters filtering tank.
The present invention adopts the regeneration ball renovation process of membrane filtration to overcome many defectives of original renovation process, compared with prior art, and the following advantage of its tool:
1, the regeneration while filtering has increased effective time of Membrane filtering machine, can continuous operation in the long mutually time;
2, no longer a large amount of clean liquid of use or other liquid recoil, and clean liquid can all use as finished product, has not had the time of emptying backwash liquid, improves filter capacity, the efficient of complete machine, and has reduced energy consumption;
3, owing to be regeneration while filtering, thereby solid phase impurity can not be attached on the filtering surface, and regeneration effect obviously is better than other renovation process, and the decline of membrane component filter capacity is delayed significantly, further improve the filtration yield of membrane component unit interval, improved filter efficiency;
4, do not had solid phase impurity to be compacted process at filtering surface, the blocked situation of filtering surface part micropore significantly reduces, and the life-span of membrane component is effectively prolonged, and has reduced user's use cost;
